4-Diode Rectifier Card

Compact Design | Reliable Rectification | Industrial Grade

The 4-Diode Rectifier Card is a robust PCB module designed to convert alternating current (AC) into direct current (DC) for a wide range of welding machines, power supplies, and electronic control systems. Featuring four high-performance diodes arranged in a bridge configuration, this board delivers smooth, reliable DC output with minimal voltage drop and heat generation.

🔧 Key Features:

• 🔄 Full-Wave Bridge Rectification – Four-diode layout ensures efficient conversion of AC to DC

• ⚡ High Current Rating – Supports continuous currents up to 50 A (typical) with suitable heatsinking

• 🌡️ Low Forward Voltage Drop – High-efficiency diodes (e.g., 1N5408 or MUR series) minimize power loss

• 🛡️ Surge Protection – Integrated transient-voltage-suppressor pads or MOV footprints to guard against spikes

• 🧲 Standard Footprint – Fits common heatsinks or chassis mounts for easy thermal management

• 🔌 Clear Input/Output Markings – Silkscreen labels for AC input (AC1, AC2) and DC output (+, –)
